Previous TDDFT simulations have shown that impurities impinging nanoscopic superfluid He droplets nucleate
vortex rings and vortex loops that start and end on the droplet surface.[1]}, [2]}
Other TDDFT simulations have addressed the capture of
impurities by vortex-hosting droplets,[3]} much as it happens in the experiments where captured impurities
form clusters along the vortex cores, helping detect the presence of vortices.[4]}, [5]}
